ON Semiconductor MC74LCX374DTR2G Octal D-Type Flip-Flop
The ON Semiconductor MC74LCX374DTR2G is a high-performance, octal D-type flip-flop integrated circuit designed for use in applications that require the capture and storage of data. This device is part of ON Semiconductor's LCX family, which is known for its low-voltage operation and high-speed interfacing capability.
Constructed with advanced silicon-gate CMOS technology, the MC74LCX374DTR2G offers a compelling mix of power-saving and speed-enhancing features. It operates with a voltage range of 2.3V to 3.6V, making it suitable for interfacing with 3.3V logic levels, while also being 5V tolerant at input ports to provide additional flexibility in mixed-voltage environments.
Each flip-flop in the MC74LCX374DTR2G has a 3-state output, which allows for connection to a bus-organized system. This is particularly useful in situations where you need to avoid bus contention or when you require the ability to put the output in a high-impedance state. The device is triggered by a positive-edge clock signal, and a clear input is provided to directly clear all flip-flops simultaneously.
Key features of the MC74LCX374DTR2G include:
- Support for 3.3V V<sub>CC with 5V tolerant inputs
- High impedance glitch-free bus loading during the entire power-up and power-down cycle
- Non-inverting outputs with bus-hold data inputs to eliminate the need for external pull-up resistors
- Power-off high impedance inputs and outputs
- Support for live insertion and withdrawal (partial power-down)
- Low static and dynamic power consumption
- ±24mA output drive at 3.3V
- Industrial operating temperature range from -40°C to +85°C
The device is supplied in a TSSOP-20 package, which is designed for space-saving on the PCB and is ideal for surface-mount technology (SMT). The MC74LCX374DTR2G is suitable for a wide range of applications, including communication systems, servers, networking equipment, and complex data processing units.
With its combination of speed, low power consumption, and robust interface capabilities, the ON Semiconductor MC74LCX374DTR2G is a reliable choice for designers looking to implement efficient data storage and transfer mechanisms in their digital systems.
